Cov tshuaj formula: BH3
Tsis tas li cov lus nug yog, hom tshuaj twg yog Borane?
Diborane(6) muaj cov qauv hauv qab no: Cov qauv no suav nrog peb-nruab choj kev sib raug zoo , nyob rau hauv uas ib qho electronpair tau sib koom ntawm peb (tsis yog ob) atoms-twoboron atoms thiab ib lub atom hydrogen. (Saib chemical bonding : Advanced yam ntawm chemical bonding : Boranes rau kev sib tham ntawm peb-centre daim ntawv cog lus .)
Ib tug kuj yuav nug, hom tshuaj tiv thaiv twg koom nrog kev sib pauv ntawm electrons? Ib qho ionic daim ntawv cog lus yog a hom tshuaj tiv thaiv tsim los ntawm electrostatic attraction ntawm ob oppositelycharged ions. Ionic daim ntawv cog lus yog tsim los ntawm ib qho cation, uas feem ntau yog hlau, thiab anion, uas feem ntau yog nonmetal. A covalent daim ntawv cog lus koom nrog ib khub electrons tau sib koom ntawm atoms.
Kuj nug, puas yog bh3 ionic lossis covalent?
BH 3 los yog hu ua borane yog ib qho covalent compound raws li nws yog tsim los ntawm kev sib koom ntawm electrons.
